My Nana was a businessman and had seven children, one of whom was my mother. My mother passed away in 2012, followed by Nana in 2021 and then my Nani in 2022. Nana passed away without a will, and while Nani may have created a will, she was not of sound mind during her final years.

We are three siblings, and our uncles do not respond properly whenever we inquire about the property and estate. When we ask our aunts about it, they say it's a matter for us siblings to sort out and that we don’t need their involvement. Since our mother is no longer with us, no aunt or uncle has informed us about our rights regarding my Nana's property.

Please guide me on what actions I can take.Moreover uncle can or may be has submitted fake documents, or affidivait for this process.
